Cosmetic composition forming after application a supramolecular polymer

ABSTRACT

The present invention relates to a care, and/or treatment, and/or make-up cosmetic composition for keratin materials, comprising, in a physiologically acceptable medium, an efficient amount of at least one linear, branched or cyclic polymer, or dendrimer, comprising:
         a -POL- polymeric backbone comprising at least two repeating patterns, and   at least two binding groups (A), attached on the polymeric backbone and adapted to create H links with one ore more partner binding groups, of an identical or different chemical nature, each coupling of two binding groups involving at least three H links.

The present invention generally relates to a care and/or treatment and/or make up cosmetic composition for keratin materials, having an increased persistence of at least one cosmetic and/or care effect provided after application by the composition, a good adhesion after application on keratin materials, and allowing for a quick, complete and selective make-up removal.

In particular, such a composition may be film-forming, and may lead after application to a film formation with the composition during drying.

In fact, in cosmetics, it is desirable to obtain a deposit on hair, skin, eye-lashes and nails, said deposit being often film-forming and providing:

-   -   either hairstyle shaping (hair);     -   or colour (hair, make-up);     -   or gloss or gloss and colour (lipsticks, mascaras, eyeliners and         nail varnish);     -   or colour and a mat aspect (foundation cream), the loss of the         mat aspect being most often due to the evolution of the colour         provided under the effect of sebum and/or sweat secretion,         making the skin shine;     -   or care, if the deposit contains a care active ingredient, for         example moisturizing, deodorant, sunscreen agents, etc.

Consequently, for some persistence of the effect being offered (colour, gloss, mat aspect, care) a large remanence of the cosmetic deposit is desired which should more particularly:

-   -   be resistant to mechanical attacks such as frictions, transfers         through contact with another object;     -   be resistant to water, sweat, tears, rain; and     -   be resistant to sebum and oils.

This is particularly true in make-up field for:

-   -   lipsticks when an extended retention of the colour and gloss and         the non transfer of the colour are looked for;     -   foundation creams, eye-lid make-ups and powders where a         retention of the colour provided is also looked for, keeping as         long as possible the mat aspect of the initial shade despite         sebum and sweat secretion as well as the non transfer.

In particular, in the case of make-up compositions, it would be highly desirable to have available coloured compositions having an increased consistency of the colour, i.e. where the colour is not degraded or made dull through mechanical attacks, water, sweat, tears, rain, sebum and oils, while keeping their other properties such as colour retention, gloss, mat aspect and care.

Moreover, it would be extremely desirable that such compositions, having an increased persistence for the effects being provided (especially colour, gloss, mat aspect, care), enhance the adhesion on keratin materials while making make-up removal easier.

The man of the art knows the use of conventional film-forming compounds, such as waxes, covalent link polymers and block polymers for the persistence of the cosmetic and/or care effect.

Thus, Patent EP-0 206 671 discloses a cosmetic composition comprising a copolymer of a fluoroalkyl(meth)acrylate and a linear alkyl(meth)acrylate and a volatile oil. The copolymer imparts to the cosmetic composition, when applied to the skin, an excellent water and oil resistance, allows for the composition to be homogeneously spread and leads to a film with a satisfactory adhesion and a high friction resistance. Additionally, the copolymers may be formulated as solid products, such as sticks or oily pencils having an extremely pleasant touch and the film-forming property of the copolymers and the retention effect for the make-up condition of the resulting film are both satisfactory.

European Patent Application EP-0 815 836 discloses a cosmetic composition comprising a fluoroalkyl(meth)acrylate copolymer and a solid oily substance which, after application, shows an excellent gloss and keeps a good gloss and colour over an extended time period. Such a composition may be used as a lipstick or mascara.

U.S. Pat. No. 5,948,393 discloses a water-in-oil make-up cosmetic composition comprising a colouring material in an internal phase and a fat soluble resin in an external phase. The fat soluble resin could be a fluororesin, a silicone resin, an aromatic hydrocarbon resin, a terpene resin, polybutene, polyisoprene, an alkyd resin and a polyvinylpyrrolidone modified polymer. The resulting make-up composition has a higher water, sweat, sebum and oil resistance.

U.S. Pat. No. 5,945,108 discloses a cosmetic composition, particularly a make-up cosmetic composition, containing a water and oil repellent powder obtained through treating the powder surface with a homopolymer or a copolymer comprising repeating (meth)acrylate patterns containing a polyfluoroalkyl group. The (meth)acrylic copolymers in the document may comprise the following monomer combinations:

-   -   (meth)acrylates containing polyfluoroalkyl and         alkyl(meth)acrylate groups;     -   (meth)acrylates containing polyfluoroalkyl and silicone         macromonomer groups; and     -   (meth)acrylates containing polyfluoroalkyl, alkyl(meth)acrylate         and silicone macromonomer groups.

The cosmetic compositions prepared through formulating such powders have higher water and oil repellent and comfort properties and prevent make-up degradations.

However, there is still a need for cosmetic compositions leading, after application on keratin materials, to deposits allowing for reconciling the cosmetic and/or care effect persistence, a good adhesion of the composition on keratin materials and a quick and complete make-up removal.

However, the Applicant has surprisingly found that a cosmetic composition comprising a polymer having a polymeric backbone comprising at least two repeating patterns and at least two binding groups attached onto the polymeric backbone, each binding group being adapted to interact with each partner binding group through the formation of at least 3H links, has an effect of increasing the persistence of at least one cosmetic and/or care effect provided after application on keratin materials by the composition.

It is meant under binding group, as defined in the present invention, any functional group comprising H link donor or acceptor groups, also called patterns.

It is meant under partner binding group, as defined in the present invention, any binding group of a polymer according to the invention adapted to create H links with one or more binding groups of another polymer according to the invention. The binding groups may have an identical or a different chemical nature. If they are identical, they can then create H links between each other. If they are different, they are selected so as to be complementary with respect to the H interactions.

The Applicant has also discovered that such a composition enhances the adhesion on keratin materials. In fact, keratin comprises groups adapted to create hydrogen interactions. Consequently, using in a cosmetic composition polymers comprising groups able each to create strong and multiples hydrogen interactions strongly enhances the adhesion of the composition on keratin.

Additionally, the Applicant has also discovered that using a selective make-up adapted to enter the deposit and break selectively the created interactions allows for a quick, complete and selective make-up removal.

Finally, the Applicant has discovered that using such polymers in a cosmetic composition leads, after application of such a composition on keratin materials, to the formation of a supramolecular polymer.

It is meant under supramolecular polymer, as defined in the present invention, a polymeric chain or network resulting from the assembly of a polymer according to the invention with at least another polymer according to the invention, each assembly comprising at least one pair of coupled binding groups.

It is meant under pair of coupled binding groups, as defined in the present invention, two binding groups belonging each to a polymer according to the invention linked together via at least three H links.

When the polymer is formulated in the presence of volatile solvents, it is possible to obtain a film formation with the composition during drying, when the polymer structure makes it possible.

It is meant under film formation, as defined in the present invention, the formation of physically cross-linked networks as films and having mechanical properties similar to those of high molecular weight polymers or chemically cross-linked networks. The physical cross-linking will provide the retention and persistence of the cosmetic and/or care effect in the same way as the chemical cross-linking, while allowing for reversibility, i.e. a possibility to totally remove the deposit via a specific make-up remover, which the chemical cross-linking does not allow.

It is known to the man of the art to use, in compositions comprising a liquid fatty phase, polymers comprising groups adapted to create hydrogen links, in order to structure the fatty phase.

Thus, U.S. Pat. No. 5,919,441, U.S. Pat. No. 5,981,680 and U.S. Pat. No. 6,051,216 as well as the International Patent Application WO 99/06473 disclose a composition comprising a silicone oil gelled by a polyorganosiloxane comprising groups adapted to give H interactions, including ester, amide, urethane, urea, thiourea groups and the combinations thereof. However, such H interaction group carrying polyorganosiloxanes are only used for gelling of the silicon oil based medium.

Similarly, U.S. Pat. No. 5,998,570 and the International Patent Application WO 00/40216, disclose polymers comprising groups adapted to create hydrogen links. Each of such groups is however only adapted to create one or two H links. Such polymers are used for gelling of the hydrocarbon oils.

None of those documents relates to a cosmetic composition comprising a polymer carrying at least two binding groups adapted to implement each at least three H interactions. Moreover, there is no mention in such documents as to the properties provided after application of the composition, such as an increased persistence of at least one cosmetic and/or care effect, a good adhesion of the composition on keratin materials and a possibility to reach a quick, complete and selective make-up removal.

Further, the International Patent Application WO-98/14504 discloses polymers comprising at least two groups adapted to create each four H interactions, reversible with the temperature. Such polymers are primarily used for their easier heat implementation, especially at a temperature where the molecules individually behave towards each other, without being involved in links. There is no mention about a cosmetic use of such polymers and the specific problems thereof.

An object of the invention is therefore to provide a care and/or treatment and/or make-up cosmetic composition for keratin materials allowing for overcoming those disadvantages.

More precisely, the object of the invention is to provide a care and/or treatment and/or make-up cosmetic composition for keratin materials comprising, in a physiologically acceptable medium, an efficient amount of at least one linear, branched, or cyclic polymer, or dendrimer, comprising:

-   -   a polymeric backbone -POL- comprising at least two repeating         patterns, and     -   at least two binding groups (A) attached onto the polymeric         backbone and adapted to create H links with one or more partner         binding groups, of an identical or different chemical nature,         each coupling of two binding groups involving at least three H         links.

It is meant under polymeric backbone, as defined in the present invention, a polymer comprising at least two covalent repeating patterns.

Both binding groups (A) may be located sidewise in the polymeric chain or at the ends of the polymeric chain.

The binding groups (A) comprise H link donor and/or acceptor groups, also called patterns, and selected amongst the following chemical functions:

wherein R represents:

-   -   a hydrogen atom, or     -   an aryl group, or     -   an aralkyl group, i.e. an aryl group substituted by a saturated,         linear or branched hydrocarbon chain, comprising from 1 to 40         carbon atoms, or     -   a saturated, linear, branched or cyclic hydrocarbon chain,         comprising from 1 to 4 carbon atoms, and/or optionally         comprising one or more heteroatoms selected amongst O, S and N,         and/or optionally substituted by one or more fluorine atoms         and/or hydroxy moieties.

Preferably, the patterns are selected amongst adenine, guanine, cytidine, thymine, pterine, ureidopyrimidone, melamine, cyanuric acid, maleimide, phthalhydrazine, isoguanine, glycoluril, uracil, acylaminopyridine, acylaminotriazine, pyridine/phenol, urazole, glutarimide, urazoylbenzoic acid groups.

Advantageously, such polymers have a polymeric backbone with a polymerisation degree ranging from 2 to 10000, and preferably from 10 to 5000.

Structure of the Polymer According to the Invention

The polymers according to the invention will be represented by: A-POL-A wherein:

-   -   A means a binding group     -   POL means the polymeric backbone.

The polymers according to the invention may have various structures.

Generally speaking, they may be:

-   -   linear or branched and functionalised only at the ends:         A-POL-A     -   linear or branched and comprising at least two groups within the         chain:         -A-POL-A-A-         or         A-A-POL-A-     -   (here one group at one end)     -   linear and comprising the A groups in side branches:

-   -   hyperbranched or dendrimeric with the A groups at the ends:

-   -   or star-shaped:

The preferred structures of the polymers according to the invention are:

1. Linear and α, ω Functional Polymers: A-POL-A

-   -   (only two groups)

Using such polymers in a cosmetic composition leads after application of the composition onto keratin materials to the formation of a supramolecular polymer as a long polymeric chain (with a high molecular weight). The polymers according to the invention are added end to end through coupling each of their binding groups with a chemically identical or self-complementary binding group (A), of another polymer: A-POL-A A-POL-A A-POL-A A-POL-A 2. Tri- or Multifunctional Polymers: trifunctional: multifunctional with side A groups

The tri- or multifunctional polymers, used alone or as a blend with difunctional polymers, can lead, after application of the composition onto keratin materials, to the formation of a supramolecular polymer comprising a physically cross-linked network, under a film aspect, and having a very good mechanical and solvent resistance. Such films may be selectively removed (make-up removal) by a solvent containing a H interaction breaker and adapted to penetrate into the deposit. The thus formed networks may be schematically represented as follows:

3. Star-Shaped, Hyperbranched or Branched Polymers (Particular Case of the Multifunctional Ones)

When used in a mixture with difunctional polymers, such polymers may lead, after application of the composition onto keratin materials, to the formation of a supramolecular polymer comprising a physically cross-linked network, identical to the networks obtained from tri- or multifunctional polymers, but with a better cross-linking probability, allowing for a lower polymer amount to be used for an identical cross-linking efficiency. The thus formed networks may be schematically represented as follows:

4. Polymer Blends with Identical Binding Groups (A) but with Their Polymeric Backbones Being of a Different Chemical Nature

Using, in a cosmetic composition, polymer blends with identical or complementary A binding groups but with their polymeric backbones being of a different chemical nature may lead, after application of the composition onto keratin materials, to the formation of copolymer type assemblies, but with physical links between the patterns instead of covalent links.

Thus, one would obtain, after the deposit of a composition comprising two α,ω bifunctional polymers (respectively with -POL₁- and -POL₂- polymeric structure) a supramolecular polymer represented by:

The polymer chainings in the supramolecular polymer are random in the present case and are equivalent to statistical assemblies.

It is however possible to obtain supramolecular polymers equivalent to alternate, blocked, multiblocked or grafted polymers, in the same way as in covalent polycondensation.

According to the invention, the supramolecular polymers are preferably statistical and obtained through a combination of -POL₁- and -POL₂- polymeric backbones such as:

-   -   -POL1- is hydrophobic, and -POL₂- is hydrophilic, so as to set         the hydrophilic/hydrophobic balance of the deposit, its water,         sweat, sebum, oil resistance, etc.;     -   the mixture of A-POL₁-A and A-POL₂-A polymers is initially         soluble or adapted to be carried in predetermined solvents; and     -   the final deposit has predetermined mechanical properties, for         example, through combination of a hard -POL₁- polymeric backbone         with a soft -POL₂- polymeric backbone.         A Binding Groups

The binding groups (A) necessarily comprise one or more functions selected amongst:

wherein R represents:

-   -   a hydrogen atom, or     -   an aryl group, or     -   an aralkyl group, i.e. an aryl group substituted by a saturated         hydrocarbon chain, linear or branched, comprising from 1 to 40         carbon atoms; or     -   a saturated, linear, branched or cyclic hydrocarbon chain,         comprising from 1 to 40 carbon atoms, and/or optionally         comprising one or more heteroatoms selected amongst O, S and N,         and/or optionally substituted by one or more fluorine atoms         and/or hydroxy moieties.

Preferably, the A binding groups comprise 5, 6 atom rings (unsaturated aromatic or heterocyclic rings), quite often consisting in C and N atoms and with conjugated double links so as to stabilize and control the H interactions.

The self-complementary binding groups (A) are selected amongst the adenine, guanine, cytidine, thymine, pterine, ureidopyrimidone, melamine, cyanuric acid, maleimide, phthalhydrazine, isoguanine, glycoluril, uracil, acylaminopyridine, acylaminotriazine, pyridine/phenol, urazole, glutarimide, urazoyl benzoic acid groups.

They can result from natural occurring or chemically modified naturally occurring derivates.

The amount of repeating patterns or polymerisation degree of the polymeric backbone according to the invention generally ranges from 2 to 100.

Preferably, the polymerisation degree ranges from 10 to 500, so as to avoid the crystallisation of the polymer according to the invention and to make it possible that the composition according to the invention have film forming properties after application.

Preferably, the -POL- polymeric backbones do not carry any other groups adapted to create H links with the binding groups (A). Stated otherwise, they do not carry any groups adapted to be competitive with the binding groups (A) for creating H links, this in order to avoid hindering or weakening the formation of the supramolecular polymer.

It is to be mentioned in particular:

1. Polydienes, Being Preferably Hydrogenated, with Hydroxy Ends and Polyolefins with Hydroxy Ends

Polydienes, being preferably hydrogenated, with hydroxyl ends and polyolefins with hydroxy ends are the preferred polymeric backbones according to the invention.

Such hydroxy ended polydienes are defined for example in Patent FR 2 782 723 from ELF ATOCHEM. They are selected in the group comprising homo- and copolymers of polybutadiene, polyisoprene and poly(1,3-pentadiene). These are oligomers with a number average molecular mass lower than 7000, and preferably ranging from 1000 to 5000, having a functionality at the hydroxy ends from 1.8 to 3 and preferably close to 2.

However, the preferred polyester-polyols according to the invention are polyester-polyols obtained through condensation with a dimeric fatty acid and/or a dimer-diol, as well as the polyester-polyols obtained through reaction with natural occurring or synthetic hydrocarbon oils carrying two to three hydroxy or epoxy groups.

2.1. Polyester-polyol Obtained Through a Condensation with a Dimeric Fatty Acid and/or a Dimer-Diol

The dimeric fatty acids are defined in U.S. Pat. No. 5,998,570, U.S. Pat. No. 3,157,681 and U.S. Pat. No. 5,411,729, respectively of the formulae (XVII), (XVIII) and (XIX):

They are more particularly sold under the trade names:

-   -   UNIDYME® by the UNION CAMP corporation, and     -   PRIPOL® (for example PRIPOL 1013) by the UNICHEMA corporation.

The dimer-diols are those defined in the article by R. HÖFER, European Coating Journal, March 2000, pp. 26-37. They have the same chemical structures as the corresponding dimeric fatty acids, only the functionalities change.

As indicated in the article by R. HÖFER, European Coating Journal, March 2000, pp. 26-37, converting dimeric fatty acids into dimer-diols may occur:

-   -   either through an hydrogenation of methyl esters of the dimeric         fatty acids,     -   or through a direct dimerization of oleic alcohol.

One can particularly mention the dimer-diols sold by the COGNIS corporation under the trade names SOVERMOL 908® (with a dimer purity of 97.5%) and SOVERMOL 650 NS® (with a dimer purity of 68%).

2.2. Polyester-polyol Obtained Through a Reaction with Natural Occurring or Synthetic Hydrocarbon Oils Carrying from Two to Three Hydroxy (or Epoxy) Groups

The preferred oils are obviously oils carrying two hydroxy groups per chain such as the monoglycerides of the structure (XX) or (XXI):

wherein R′ is a linear or branched alkyl chain, such as for example glycerol monostearate.

Such glycerol monoesters correspond for example to the compounds:

wherein:

-   -   D represents —O—, and

One can also mention naturally occurring oils (Vernonia) or synthetic oils comprising epoxy groups.

3. Polycarbonates Initially with α,ω-OH Ends

The polymeric backbones according to the invention may also be advantageously selected amongst polycarbonates with α,ω-OH ends.

The polycarbonates with α,ω-OH ends may be obtained through a reaction between a diol which may be selected amongst 1,3-propanediol, 1,4-butanediol, 1,6-hexanediol, diethyene glycol, and tetraethylene glycol, and a diarylcarbonate such as for example a diphenylcarbonate, or phosgene.

4. Polyalkylene oxides Initially with α,ω-OH Ends

9. Vinyl or (meth)acrylic oligomers or polymers Initially with —OH, —NH₂, —NHR, —SH reactive groups

According to the invention, it is also possible to use as a polymeric backbone vinyl or (meth)acrylic oligomers or polymers initially with —OH, —NH₂, —NHR reactive groups (where R is as previously defined), or —SH.

Such polymers are generally selected amongst homo- or copolymers with —OH, —NH₂, —NHR side groups (where R is such as previously defined).

These are preferably oligomers with a number average molecular weight of less than 10000, obtained through copolymerisation of one or more vinyl and allyl monomers, olefins, vinylether, (meth)acrylic acids or esters or amides, with at least one co-reactive monomer carrying at least one group selected amongst —OH, —NH₂ and —NHR.

Examples include homo- and copolymers obtained through polymerisation with:

-   -   a hydroxyalkyl(meth)acrylate, such as 2-hydroxyethyl acrylate,         or     -   the vinyl alcohol (obtained through hydrolysis of the vinyl         acetate patterns of the polymer), or     -   the allyl alcohol,     -   the vinylamine, or     -   the allylamine.

But it is also possible to use those (homo- and co-) oligomers carrying α,ω-OH reactive ends.

The polymerisation of methacrylic monomers (acids, esters or amides) in the presence of a 2-mercaptoethanol transfer agent (HS—CH₂—CH₂—OH) leads to functionalised oligomers at each α,ω end by a hydroxyethylsulfide group: HO—CH₂—CH₂—S-POL-S—CH₂—CH₂OH où POL désigne:

wherein R″ represents a group selected amongst the alkyl, aryl, aralkyl, alkenyl, alkoxy, alkoxyalkyl, alkoxyaryl or phenyl groups.

Such a polymerisation is disclosed in the article by G. REUSMANN, Eur Coat. J., 9, 52-53, 56, 58 (1999) and also N. KEBELKAMP A Farbe Lack, 105, (2), 24-26, 28-29 (1999) disclosing the synthesis of such α,ω-polymethacrylate-diols and their use for producing polyurethanes.

10. Cellulose Derivates

The POL polymeric backbone according to the invention may also be selected amongst cellulose derivates.

Amongst them, one can mention cellulose hydroxyalkylethers and alkylethers (or guar, etc.), cellulose esters (such as acetates, propionates, butyrates and mixed esters), and nitrocellulose.

11. Di- Tri-, Tetra- and More Generally Polysaccharides or the Derivates Thereof

The POL polymeric backbone according to the invention may also be selected amongst di-, tri-, tetra- and more generally polysaccharides or the derivates thereof, in particular ethers and esters.

12. Hyperbranched or Dendrimers, Initially with Reactive Ends of the —OH, —NH₂, —NHR and —SH Type

Finally, the POL polymeric backbone according to the invention may be selected amongst the hyperbranched or dendrimers, initially with reactive ends of the —OH, —NH₂, —NHR and —SH type.

The dendrimers (from the Greek dendron=tree) are “arborescent” polymeric molecules, i.e. highly branched, invented by D. A. Tomalia and its staff at the early nineties (Donald A. Tomalia and al., Angewandte Chemie, Int. Engl. Ed., vol 29, n° 2, pp. 238-175). These are molecular structures built around a generally polyvalent central pattern. Around said central pattern are chained, in concentric layers and according to a perfectly determined structure, chain extending branched patterns also giving rise to symmetrical monodispersed macromolecules with a well defined chemical and stereochemical structure. Polyaminoamine type dendrimers are commercialised for example under the trade name STARBUST® by the DENDRITECH corporation.

The hyperbranched polymers are polycondensates, generally of the polyester, polyamide or polyethyleneimine type, obtained from multifunctional monomers, which have an arborescent structure similar to that of dendrimers, but much less regular than the latter (see for example International Patent Applications WO-A-93/17060 and WO-96/12754).

The PERSTORP corporation sells under the trade name BOLTORN® hyperbranched polyesters. One will also find under the trade name COMBURST® from the DENDRITECH corporation hyperbranched polyethyleneimines and hyperbranched polyesteramides with hydroxy chain ends commercialised under the trade name HYBRANE® by the DSM corporation.

As previously indicated, after functionalisation of such dendrimers or hyperbranched polymers, with their ends being attached by binding groups -(A), they will be preferably used as a blend with other A-POL-A polymers according to the invention having only two groups (A) per molecule, so as to make cross-linked deposits, after application and drying of the cosmetic composition cosmetic.

Attachment of the Binding Groups (A) on the POL Polvmeric Backbone

The attachment chemical reactions mentioned herein are not limitative, but are only given by way of illustration.

According to a first embodiment of the invention, the binding groups are attached onto POL polymeric backbones comprising labile hydrogen groups such as —OH, —NH₂, —NHR (wherein R is such as previously defined) or —SH, via the functionalisation of the binding group (A) by an isocyanate. Such a reaction comprises the following steps of:

-   -   functionalizing the group A by an isocyanate according to the         reaction scheme:

-   -   and then reacting with a POL polymeric backbone comprising at         least two labile hydrogen groups such as —OH, —NH₂, or —SH.

As an example, one can mention the attachment reaction for an ureidopyrinidone group, such as for example 6-methylisocytosine, onto a POL polymeric backbone with a HO-POL-OH or H₂N-POL-NH₂ structure:

Such a reaction is described in further detail in the article by B. J. B. FOLMER, Adv. Mater, 12, 874-78 (2000).

It is also possible to perform the reverse reaction by prefunctionalising the polymeric backbone with a labile hydrogen group such as —OH, NH₂, —NHR (where R is such as previously defined) or —SH by a diisocyanate.

As an example, one can mention the reaction of a polymeric backbone POL with a following diisocyanate:

Such a reaction is also described in the article by B. J. B. FOLNER, Adv. Mater, 12, 874-78(2000). This article also indicates the attachment conditions of ureidopyridimidone groups, for either of the two pathways described hereinabove, on POL polymeric backbones of the following nature:

-   -   polyoxyalkylene (for example: HO—POE/PPO—OH),     -   polyester (for example: butyl polyadipate with —OH end),     -   polycarbonate (for example: hexyl polycarbonate) with α,ω-OH         end),     -   copoly(ethylene/butylene) with α,ω-OH ends.

Those two attachment pathways for the ureidopyrimidone groups may be transposed to all the -POL- polymeric backbones according to the invention comprising two or more —OH, —NH, —NHR, and —SH groups.

The attachment conditions for the 6-methylisocytosine groups, via the isophorone diisocyanate on POE/PPO block polymers with —OH ends are described in detail in the article by R. F. M. LANGE, J. Polymer Sci: Part A, Polym. Chem., 37, 3657-70 (1999) as well as in the International Patent Application WO 98/14504.

Alternatively, the binding groups (A) are attached onto the polyorganosiloxanes through hydrolyse. Such a reaction comprises the following steps of:

-   -   functionalizing (A) by an allyl —CH₂—CH═CH₂ group by direct         synthesis→CH₂═CH—CH₂-(A);     -   and then reacting with an organosiloxane carrying two or more         hydrogenosilane —S_(i)H groups as follows:

An example includes the hydrosilylation reaction described in the article by R. P. S. SIVBESMA, Science, 278, 1601-04 (1997):

followed with the protection of phenyl groups through hydrogenation on palladium.

Such protection, hydrosilylation and then deprotection reactions are detailed in the article by J. H. K. K. HIRSCHBERG, Macromolecules, 32, 2696-2705 (1999) and in the International Patent Publication WO-98/14504 from DSM.

-   -   hydrocarbon vegetable oils with a high triglyceride content         consisting in esters of fatty acids and glycerol where the fatty         acids may have variable chain lengths, the latter being linear         or branched, saturated or unsaturated; with such oils being         particularly wheatgerm, corn, sunflower, karite, castor, sweet         almond, macadamia, apricot, soja, rapeseed, cotton, alfalfa,         poppy, potimarron, sesame, marrow, avocado, hazelnut, grape or         blackcurrant seeds, onager, millet, barley, quinoa, olive, rye,         carthame, candlenut, passiflora and Muscat rose-tree oils; or         also caprylic/capric acid triglycerides such as those sold by         the Stearineries Dubois corporation or those sold under the         trade names Miglyol 810, 812 and 818 by the Dynamit Nobel         corporation;     -   synthetic oils of the formula R¹COOR² wherein R¹ represents the         remainder of a linear or branched higher fatty acid comprising         from 7 to 19 carbon atoms, and R² represents a branched         hydrocarbon chain containing from 3 to 20 carbon atoms, such as         for example the Purcellin oil (cetostearyl octanoate), isononyl         isononanoate, C₁₂-C₁₅ alkyl benzoates;     -   synthetic esters and ethers such as isopropyl myristate,         ethyl-2-hexyl palmitate, octanoates, decanoates or ricinoleates         of alcohols or polyalcohols;     -   hydroxy esters such as isostearyle lactate, di-isostearyl malate         and pentaérythritol esters;     -   C₈ à C₂₆ fatty alcohols such as oleic alcohol; and     -   the mixtures thereof.

The apolar oils include:

-   -   volatile or not, linear or cyclic, silicone oils being liquid at         room temperature, such as polydimethylsiloxanes (PDMS)         comprising alkyl, alkoxy or phenyl groups, either pendant and/or         at the end of the silicone chain and having from 2 to 24 carbon         atoms; phenyl silicones, such as phenyl trimethicones, phenyl         dimethicones, phenyl trimethylsiloxy diphenylsiloxanes, diphenyl         dimethicones, diphenyl methyldiphenyl trisiloxanes and         2-phenylethyl trimethylsiloxysilicates;     -   hydrocarbons or fluorinated hydrocarbons and/or fluorocarbons,         either linear or branched, from a synthetic or mineral origin,         such as volatile oils, like paraffin oils (for example         isoparaffins), and aliphatic hydrocarbons (for example         isododecane), or not volatile oils and the derivates thereof,         petroleum jelly, polydecenes, hydrogenated polyisobutene such as         parleam, squalane and the mixtures thereof.

The solvents are preferably present in proportions ranging from 1 to 90% in weight, and in particular from 5 to 70% in weight based on the total weight of the composition.

The solubility of the polymers according to the invention will be controlled by the selection of the -POL- polymeric backbones and binding groups (A).

The polymers of the invention may in some cases already interact between themselves physically (creating a network of H interactions) in some solvents or mixtures of solvents. This depends upon the nature and proportions of solvents or mixtures of solvents being used. This can lead to an unwanted increase of the viscosity of the formula and hinder its application (for example a lotion, an aerosol, etc.).

To overcome such a viscosity problem, one can operate in two ways:

-   -   either solubilizing the polymer according to the invention in a         volatile solvent adapted to create H interactions H with binding         groups (A) of the polymers, for example using short alcohols,         volatile polyols and water,     -   or using a diphasic solubilizing medium, as for example a         water-in-oil (E/H) or oil-in-water (H/E) emulsion and a couple         of selective polymers according to the invention with their         binding groups and their polymeric backbones being of different         chemical natures, each polymer being dissolved in a phase         differing from the other (one in water, the other one in oil).

The couple of A-POL₁-A and B-POL₂-B polymers is then selected so that:

-   -   each of the binding groups (A) does not create any H interaction         with itself, but only with (B),     -   each of the binding groups (B) does not create any H interaction         with itself, but only with (A),     -   the binding groups (A) and (B) create H interactions only when         they come into contact together, and     -   the -POL₁- and -POL₂- polymer backbones are selected so that the         A-POL₁-A and B-POL₂-B polymers may each be carried in a distinct         phase of the emulsion, so that they cannot react in the         emulsion.

The interaction between both polymers will only occur upon application, on the condition however that the solubilizing media should be volatile solvents or can penetrate into the keratin support.

As is known, the composition of the invention may also contain the usual builders common in the cosmetic and dermatological fields as long as the builder does not alter the properties looked for the composition of the invention, such as hydrophilic or lipophilic gellants, hydrophilic or lipophilic care active ingredients, preservatives, antioxidants, perfumes, fillers, neutralizing agents, other polymers than those previously defined, emulsifiers and co-emulsifiers.

The amounts of those various builders are those conventionally used in the subject fields, and for example, ranging from 0.01 to 30% of the total weight of the composition. Such builders, depending upon their nature, may be introduced into the fatty phase, the aqueous phase, the lipidic vesicles and/or the nanoparticles.

The emulsifiers and co-emulsifiers optionally used in the composition under the form of an emulsion are selected depending on the emulsion type (E/H or H/E) amongst those conventionally used in the subject field.

Such emulsifiers and co-emulsifiers are preferably present in the composition in a proportion ranging from 0.3 to 30% in weight, and preferably from 0.5 to 20% in weight based on the total weight of the composition.

Emulsifiers and co-emulsifiers useful in the invention include for example esters of fatty acids and polyols such as PEG-100 stearate, PEG-50 stearate and PEG-40 stearate; sorbitan tristearate, oxyethylenated sorbitan stearates comprising for example 20 to 100 EO, and for example those available under the trade names Tween® 20 or Tween® 60 and the mixtures thereof, such as the mixture of glyceryl monostearate and polyethylene glycol stearate (100 EO) commercialized under the trade name SIMULSOL 165® by the SEPPIC corporation.

Silicone emulsifiers can be also mentioned such as dimethicone copolyols and alkyl dimethicone copolyols. One can mention for example as dimethicone copolyol, the mixture of dimethicone copolyol, cyclomethicone and water (10/88/2), commercialized by the Dow Corning corporation under the trade name DC3225C® or DC2-5225C®, and as alkyl dimethicone copolyol, those having an alkyl moiety comprising from 10 to 22 carbon atoms, such as cetyl dimethicone copolyol like the product commercialized under the trade name Abil EM-90® by the Goldschmidt corporation and the mixture of dimethicone copolyol and cyclopentasiloxane (85/15) commercialized under the trade name Abil EM-97® by the Goldschmidt corporation; lauryl dimethicone copolyol and for example the mixture of approximately 91% lauryl dimethicone copolyol and approximately 9% isostearylic alcohol, commercialized under the trade name Q2-5200® by the Dow Corning corporation, and the mixtures thereof.

Of course, the man of the art will take care to select the possible compound(s) to be added to the compositions according to the invention, as well as the concentration thereof, so that the advantageous properties intrinsically associated with the compositions according to the invention are not or substantially not altered by the contemplated addition.

Example 3 Preparation of a Polyester Having Two α,ω-OH Ends with Ureidopyrimidone Groups

A) Synthesis of the Polyester with Initial α,ω-OH Ends: Sebacate/Terephthalate Copolymer of Neopentylglycol (MW=600-700) and with α,ω-OH Ends

Reactive Agents

Dimethyl terephthalate 116.4 g (0.6M) Dimethyl sebacate   138 g (0.6M) 2,2-dimethyl-1,3-propanediol 274.6 g (2.64M) (or neopentylglycol) Zinc acetate dihydrate  1.6 g (0.3% in weight/reactive agent) pure 1, dichloroethane    2 l Permuted water    2 l Operating Mode

A 500 ml cylindrical reactor is used, which is provided with a nitrogen inlet, a thermometer and a distillation assembly. The reactor is heated in a Wood alloy bath.

In the reactor are introduced the 2,2-dimethyl-1,3-propanediol (melting point 126-128° C.) and the previously molten methylsebacate (melting point 25-28° C.). The mixture is heated from room temperature to 150° C. in one hour. As soon as the reaction medium becomes clear at approximately 100° C., the dimethyl terephthalate is added. As soon as a 150° C. temperature is reached in the reaction, then the zinc acetate is added. The synthesis is allowed to proceed for three hours at 150° C. while collecting the formed methanol. Then, the temperature is increased to 200° C. in forty-five minutes and is then held for three hours at 200° C. The distillation of the methanol goes on proceeding during the whole condensation.

At the end of the three hours at 200° C., it is allowed to return to room temperature under reduced stirring. As soon as the inner temperature reaches 50° C., 300 ml of 1,2-dichloroethane are added.

The synthesis solution is recovered and then diluted with 1.7 l of 1,2-dichloroethane. The excess 2,2-dimethyl-1,3-propanediol is then extracted twice with one litre of permuted water. During those extractions, it may happen that an interfacial emulsion is formed. Such an emulsion is easily removable through heating of the water used during the extraction. The organic phase is recovered and dried on anhydrous sodium sulfate. The 1,2-dichloroethane is filtered and evaporated until recovery of the dry product.

The polymer has the form of a paste at room temperature and becomes liquid at 50° C.
